The fastest way to find your account number
Your checking account number is printed on the bottom left of every check you write — it's the middle set of numbers between your routing number and the check number. If you have a checkbook handy, look at any check and you'll see it there. The account number is usually 10 to 12 digits long, though the exact length varies by bank.
If you don't have checks or prefer not to dig through a drawer, log into your bank's website or mobile app. Your account number appears on the account summary page, usually labeled as "Account Number" or "Checking Account Number." Most banks show it prominently near your account balance.
You can also call your bank's customer service line — the number is on the back of your debit card or on your bank statements — and a representative will read it to you over the phone. Have your ID ready, as banks verify your identity before sharing account details.
Key Takeaways
- Your account number appears on the bottom left of any check you have, printed between the routing number and check number.
- Logging into your bank's website or app shows your account number on the account summary or dashboard page.
- Your bank's customer service line can provide your account number by phone after they verify your identity.
- Bank statements — whether paper or digital — list your account number at the top or in the account details section.
- Some banks print the account number on your debit card, though not all do.
Finding it on your bank statements
Paper statements and digital statements both display your account number in the account information section, usually near the top of the first page. Look for a line labeled "Account Number" or "Your Account." The number may also appear in the header with your name and address.
If you receive statements by mail, check the most recent one in your files. If you bank online, log in and look for a "Statements" or "Documents" section — most banks let you download or view statements from the past several years. Digital statements are often easier to search: use your browser's find function (Ctrl+F on Windows, Cmd+F on Mac) and search for "account number" to jump straight to it.
Using your debit card
Some banks print your account number on the front or back of your debit card, though this is less common than it used to be for security reasons. If yours does, it will be a separate line of numbers from your card number. The card number itself (the 16 digits on the front) is not your account number.
If your debit card doesn't show the account number, don't assume your bank doesn't have one — it just means they chose not to print it there. Use one of the other methods instead.
What to do if you can't find it
If you've checked your checks, statements, and online account and still can't locate it, contact your bank directly. Call the number on the back of your debit card or visit a branch in person with your ID. The bank will confirm your identity and provide the number immediately.
Some banks also send account information by email or text if you request it through their app or website. Check whether your bank offers this option before calling — it may be faster than waiting on hold.
Why you need your account number
Your account number is required for direct deposit, wire transfers, setting up automatic bill payments, and when you need to give payment instructions to employers, creditors, or other organizations. It's also needed if you're transferring money between your own accounts at different banks.
Your account number alone is not enough for someone to withdraw money from your account — they also need your routing number and usually additional verification. However, treat it as sensitive information and don't share it with people you don't trust.
Account number vs. routing number
Your account number identifies your specific account at your bank. Your routing number identifies the bank itself. Together, they form the complete address for your account. On a check, the routing number comes first (the leftmost set of numbers), then your account number, then the check number on the right.
When you're setting up direct deposit or a wire transfer, you'll need both numbers. Some forms ask for them separately; others ask for them together. If you're unsure which number goes where, ask the person or organization requesting the information — they can tell you which field needs which number.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 16 digits on the front of your debit or credit card. Your account number is a separate number, usually 10 to 12 digits, that identifies your checking or savings account. Some cards print the account number on them, but most don't.
Can someone take money from my account if they know my account number?
Not without additional information. Your account number alone doesn't give access to your money. Someone would also need your routing number and usually some form of verification or authorization. Still, don't share your account number with people you don't trust.
What if my bank merged or changed names?
Your account number typically stays the same after a merger. Check your most recent statement or log into your online account to confirm. If you're unsure, call the bank and they'll confirm your current account number.
Do I have a different account number for each account I have?
Yes. If you have a checking account and a savings account at the same bank, each one has its own account number. When you need to move money between them or set up transfers, you'll need to specify which account by its number.
